Here are a few strategies that might help:- Leverage Industry Benchmarks: Many investors use a percentage of gross rental income as a quick estimate for operating expenses.

Loans are approved based off of the rental income of the property.

I started real estate investing by house hacking and then getting into rentals from there.

They charge $1250 for properties under $1mm for a 1 to 1 exchange and if you have another property to move your funds into, they charge $550/additional property.

My mentor told me I was still charging too low for the value I was providing. 

I've actually had an investor give two of the properties back to me after religiously making his payments for 3 years on time but got a set of bad tenants and could not maintain the rentals. 

You can include moving and storage costs in the charges.

Realtors typically pre-screen rental clients to make sure their time is not going to be wasted.

Id recommend connecting with someone who can help you shop more investment-specific/rental programs on a national scale.

In my area, they charge transfer tax on the assessed value rather than the LOW sale price.
